Yes. I briefly owned a X3M prior to my M50i.
The X3M had a very noticeable lack of torque below 2K RPM. Not sure if I would call it turbo lag, but it was there nonetheless. Once it kicked in though, it was insanely quick. It liked to run at higher RPM ranges for sure. The M50i feels 90% as quick to me.
The brakes were much better in the X3M, as was the handling -- but the ride quality in the X3M was so bad, it was one of the primary reasons I got rid of it.
The X5 M50i with 2-axle air is night and day better for *me*. Yes, you do sacrifice sports-car like handling, but the M50i in Sport suspension mode is plenty for the way I drive. The interior on the M50i is much nicer, and comfort is better all around. Exhaust in the M50i sounds much better to my ears as well.
Overall, I am much happier with the M50i than the X3M.
